Trailer alignment starts at the trailer frame hangers and then inspecting or replacing parts. We used to have an alignment kit but the manufacturer decided not to continue it. Check the shackle strap holes first and then the hangers for elongated holes. Then check springs for broken leafs or bent springs. Next check equalizers and linkages. Finally check the axle spindles as they can get bent by hitting things like curbs.

Unfortunately misalignment normally means replacing one or more parts so you don't get a trailer that tracks incorrectly or has tire wear issues. Take measurements and compare the right side to the left for differences.
